Description

[0002] Due to the various forms of roadbed slope protection, many types of materials, narrow construction sites, and large height differences, choosing the right material transportation method has an important impact on the control of construction costs and the improvement of construction efficiency. The traditional material transportation method is to use winch equipment or manual lifting, lifting, and handling. The use of winch equipment to transport materials requires large equipment investment, high installation and disassembly costs, and slow turnover speed; the use of manual lifting, lifting, and handling of materials has high safety risks, high labor intensity for operators, high construction costs, and low efficiency.

[0003] At present, mechanical creepers are used to transport materials during slope reinforcement. However, before use, supports need to be installed on the slope to ensure the rigidity of the mechanical creeper track.

At the same time, the supports cannot be moved once implemented, which also limits the scope of use of mechanical creepers. The track length used for hopper operation is generally 8m, with poor adaptability to different slope heights and inconvenient transportation. It also needs to be customized for special areas, with poor adaptability to slope heights, and the customized track cannot be used for other projects after the project is completed, resulting in waste.

DETAILED DESCRIPTION

[0026] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.

[0027] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Specific implementation of the accompanying drawings Specific implementation of the accompanying drawings.

[0028] Embodiment The present invention provides a material lifting device for slope reinforcement, as Figure 1-Figure 10 shown, which includes two first platforms 1. The first platform 1 is a steel frame structure. A traveling mechanism 3 is installed on both of the two first platforms 1. The traveling mechanism 3 enables the lifting device to move flexibly in the horizontal direction or the extending direction of the slope, improving the flexibility and efficiency of construction. The first platform 1 is rotatably connected to the telescopic structure 4 to adapt to slopes with different gradients, improving the adaptability of this structure.

[0029] The telescopic structure 4 provides a carrier for the operation platform 2 to move on the slope and supports the operation platform 2 to move in the height direction of the slope. Its specific structure includes a fixed frame 45 and two telescopic frames 48. The fixed frame 45 is a steel frame structure. The cross-section of the telescopic frame 48 is in the shape of "匚". The width of the fixed frame 45 is the width of the "匚" - shaped area of the telescopic frame 48. The two telescopic frames 48 are respectively slidably arranged on the fixed frame 45, and the fixed frame 45 is placed within the "匚" - shaped area of the telescopic frame 48. To prevent the telescopic frame 48 from separating from the fixed frame 45, baffles need to be provided at the two vertical ends of the telescopic frame 48, and the baffles are integrally formed with the telescopic frame 48. Two second push rods 39 respectively connected to the telescopic frames 48 are installed on the side wall of the fixed frame 45. The body of the second push rod 39 is fixed to the fixed frame 45 by bolts, and the telescopic end of the second push rod 39 is rotatably arranged on the side wall of the telescopic frame 48 through a pin shaft. In this way, when an operator controls the telescopic frame 48 to reciprocate on the fixed frame 45 through the second push rod 39, the effective length of the telescopic structure 4 can be adjusted to adapt to slopes with different heights, improving the adaptability of this structure.

[0030] The operation platform 2 provides an activity area for the operator when working on the slope. The operation platform 2 can carry some objects for reinforcing the slope, and under the push of the pushing mechanism, the operation platform 2 can move along the extension direction of the slope to lift the object or the operator to a predetermined height. The operation platform 2 is slidably arranged on the side wall of the telescopic structure 4, and a control mechanism for controlling the rotation of the operation platform 2 relative to the telescopic structure 4 is arranged on the side wall of the telescopic structure 4, which can keep the operation platform 2 balanced on the telescopic structure 4. The operation platform 2 includes a guiding frame 9, a displacement seat 11 and a displacement table 32. The guiding frame 9 is installed on the displacement seat 11, and two second guiding wheels 34 are installed on the side wall of the displacement seat 11. The second guiding wheels 34 are fixed on the side wall of the displacement seat 11 by bolts. Two guiding grooves 35 adapted to the second guiding wheels 34 are opened along the extension direction of the telescopic structure 4. The cross-sectional area of the guiding groove 35 is U-shaped, and limiting grooves are opened on two opposite inner side walls of the guiding groove 35. The shaft rods of the second guiding wheels 34 are embedded in the limiting grooves, and the limiting grooves are used to prevent the second guiding wheels 34 from jumping out of the guiding groove 35 when moving in the guiding groove 35. The displacement table 32 is slidably arranged in the guiding frame 9 in a shape of匚. Two guiding rods 10 connected to the displacement seat 11 are penetrated through the side wall of the displacement table 32. Under the limitation of the guiding rods 10, the displacement table 32 can move smoothly in the guiding frame 9 and will not be separated from the guiding frame 9. The body of the control mechanism is slidably arranged in the guiding groove 35, and the telescopic end of the control mechanism is connected to the displacement table 32.

[0031] In some technical solutions of the present invention, the control mechanism includes two first push rods 5 arranged in pairs and a mounting seat 6. Two first guiding wheels 33 are installed on the side wall of the mounting seat 6. The first guiding wheels 33 are rotatably arranged on the side wall of the mounting seat 6. The bodies of the two first push rods 5 are fixedly connected to the side wall of the mounting seat 6. A support seat 12 connected to the telescopic ends of the two first push rods 5 is arranged on the side wall of the displacement table 32. The telescopic ends of the first push rods 5 and the support seat 12 are rotatably connected by a pin shaft. The operator can control the telescopic movement of the first push rods 5 to make the operation platform 2 perform circular motion around the rotation point formed by the displacement seat 11 with the telescopic structure 4, so that the horizontal angle of the operation platform 2 changes and always maintains relative balance with the horizontal plane, providing a relatively flat operation surface for the operator and improving the safety during construction operations.

[0032] Preferably, rectangular grooves are formed on both the fixed frame 45 and the two telescopic frames 48, and the provided guiding groove 35 is composed of rectangular grooves respectively located on the fixed frame 45 and the two telescopic frames 48.

[0033] A walking mechanism 3 is installed on the first platform 1. The walking mechanism 3 can make the first platform 1 and the telescopic structure 4 move along the extension direction of the slope when the above structure is transferred to the construction position on the slope, so that the operator does not need to frequently transfer the position of the first platform 1 and the telescopic structure 4 on the slope, which speeds up the construction progress and improves safety. The walking mechanism includes a frame 27, on which two sets of crawler structures are installed. The crawler structure includes crawlers 28, road wheels 29 and driving wheels 30. The road wheels 29 and the driving wheels 30 are both rotatably arranged on the same side of the frame 27 through load-bearing bearings and rotating shafts. The crawlers 28 are wound around the road wheels 29 and the driving wheels 30 and are connected end to end. The frame 27 is provided with a third driving motor 31 that is transmission-connected to the driving wheel 30. The third driving motor 31 is a high-power motor that can provide sufficient power for the driving wheel 30. In addition, the width of the crawler 28 is relatively wide, which can increase the contact area between the crawler 28 and the ground, and avoid the risk of the device slipping on the slope when the above structure is overlapped on the upper and lower sides of the slope.

[0034] The traveling mechanism 3 can rotate on the ground relative to the first platform 1 , thereby changing the traveling direction of the traveling mechanism 3 .

[0035] The two first platforms 1 are both rotatably connected to the corresponding telescopic frames 48 through pins, and the frames 27 in the two walking mechanisms 3 are fixedly connected to the corresponding first platforms 1 through bolts. A positioning mechanism is provided between the walking mechanism 3 and the corresponding first platform 1. The positioning mechanism is used to adjust the inclination angle of the walking mechanism 3 on the ground, so that the first platform 1 located on the upper side of the walking mechanism 3 maintains relative balance on the horizontal plane, and avoids the above structure from overturning during the transfer process, causing serious construction accidents. The telescopic structure 4 is provided with a pushing mechanism for driving the working platform 2 to move along the extension direction of the telescopic structure 4. The pushing mechanism can drive the working platform 2 to reciprocate on the telescopic structure 4 along the extension direction of the slope, and lift the object or operator to a predetermined height. In the process of pushing the working platform 2 to move on the telescopic structure 4, the pushing mechanism can also use the working platform 2 to apply downward pressure to the chain structure in the pushing mechanism, so that the chain structure can achieve the purpose of self-locking under the action of gravity.

[0036] In some technical solutions of the present invention, the pushing mechanism includes a chain structure, which includes a plurality of first chain blocks 14, and a second chain block 15 is rotatably provided between any two adjacent first chain blocks 14, and a rectangular rotating groove is provided on both sides of the first chain block 14, and a rotating part integrally formed therewith is provided on both sides of the second chain block 15, and a rotating rod 13 is fixedly provided on the rotating part, and the rotating rod 13 is rotatably provided in an axial hole provided on the inner wall of the rotating groove, and a part of the rotating rod 13 extends outward through the axial hole, and a guide member 7 is installed on the telescopic structure 4, and a guide channel is provided in the guide member 7, and the chain structure is penetrated in the guide channel, and the first chain block 14 at the end of the chain structure is connected to the displacement seat 11. A driving gear 8 is rotatably provided on the telescopic structure 4, and a through hole communicating with the guide channel is provided on the side wall of the guide member 7, and a part of the driving gear 8 is embedded in the through hole, and the extended end of any one of the rotating rods 13 is embedded in the tooth groove of the driving gear 8. A connecting motor that is driven by the driving gear 8 is installed on the outer side wall of the telescopic structure 4, and the motor is a high-power motor.

[0037] The working principle of the pushing mechanism is as follows: first, the motor is started, and the motor makes the driving gear 8 rotate counterclockwise on the telescopic structure 4, and applies an oblique upward thrust to the rotating rod 13 embedded in the tooth groove of the driving gear 8, so that the chain structure moves obliquely upward along the guide channel in the guide member 7, and applies a thrust to the displacement seat 11, so that the working platform 2 moves along the extension direction of the guide groove 35, thereby lifting the working platform 2 to a predetermined height. Similarly, in the process of pushing the working platform 2 to move on the telescopic structure 4, the working platform 2 can also be used to apply downward pressure to the chain structure in the pushing mechanism, so that the chain structure can achieve the purpose of self-locking under the action of gravity.

[0038] In some technical solutions of the present invention, the positioning mechanism includes a connecting seat 16 installed on the first platform 1, the connecting seat 16 is fixedly connected to the first platform 1 by bolts, and a mounting opening adapted to the connecting seat 16 is opened on the bottom wall of the first platform 1. A first mounting plate 17 and a second mounting plate 24 integrally formed therewith are installed on the side wall of the connecting seat 16, a rotating frame 20 is provided on the first mounting plate 17 through a shaft rod rotation, a deflection body 21 is provided in the U-shaped area of ​​the rotating frame 20 through a shaft rod rotation, a first driving motor 19 drivingly connected to the rotating frame 20 is installed on the first mounting plate 17, a first reducer 18 is installed on the output end of the first driving motor 19, a housing of the first reducer 18 is connected to the first mounting plate 17, and the output end of the first reducer 18 is drivingly connected to the shaft of the rotating frame 20 through a coupling. A control frame 26 is provided on the second mounting plate 24 through a shaft rotation, a second drive motor 23 is installed on the second mounting plate 24 and is transmission-connected to the control frame 26, a second reducer 22 is installed on the output end of the second drive motor 23, a housing of the second reducer 22 is connected to the second mounting plate 24, and the output end of the second reducer 22 is transmission-connected to the shaft of the control frame 26 through a coupling. An adjustment frame 25 is provided on the free end of the control frame 26 through a shaft rotation, the adjustment frame 25 is rotationally connected to the side wall of the deflection body 21 through a shaft, and the deflection body 21 is detachably connected to the frame 27 through bolts.

[0039] By means of the above structure, when the deflection body 21 is controlled to deflect along the X-axis or Y-axis in space, the traveling mechanism 3 rotatably connected to the deflection body 21 can also be made to deflect along the X-axis or Y-axis. Thus, the inclination angle of the traveling mechanism 3 on the ground is changed to adapt to the ground with complex terrain, and the first platform 1 located on the upper side of the traveling mechanism 3 is kept relatively balanced on the horizontal plane, so as to avoid the overturning of the above structure during the transfer process, which may cause serious construction accidents.

[0040] In some technical solutions of the present invention, a guide ring 37 is rotatably provided between the side walls opposite to the first platform 1 and the frame 27. The guide ring 37 is embedded in the side wall of the first platform 1. A plurality of buffers 36 are installed on the side wall of the frame 27. The buffer 36 is a hydraulic push rod with self-rebound capability. The telescopic end of the buffer 36 is hinged with the guide ring 37. The body of the buffer 36 is sleeved with an adjustment spring 46 that abuts against the first platform 1. The body of the buffer 36 is fixedly provided with a limit seat. One end of the adjustment spring 46 abuts against the limit seat, and the other end of the adjustment spring 46 abuts against the first platform 1. The above structure can improve the stability of the first platform 1 on the frame 27, provide strong support for the first platform 1, and prevent the first platform 1 from becoming unstable on the walking mechanism 3, which affects the safety of the operation of the present structure.

[0041] Preferably, a limit member is installed on the vehicle frame 27, the cross section of the limit member is U-shaped, a slide groove is provided on the side wall of the limit member, and the body of the buffer 36 is slidably arranged in the slide groove through a pin shaft.

[0042] In some technical schemes of the present invention, a mounting hole is provided on the side wall of the frame 27, and a shaft sleeve 38 is installed in the mounting hole. A guide cylinder 44 is rotatably provided on the deflection body 21 through a bearing, and the guide cylinder 44 is threadedly connected to the shaft sleeve 38. An internal thread is provided on the inner side wall of the shaft sleeve 38, and an external thread meshing with the internal thread is provided on the outer side wall of the guide cylinder 44. A plurality of guide holes are arranged around the side of the shaft sleeve 38 away from the guide cylinder 44, an inner step connected to the guide hole is provided in the shaft sleeve 38, and a push rod 41 is passed through the guide hole. A mounting ring 47 is slidably provided in the shaft sleeve 38, and the push rod 41 is fixedly connected to the mounting ring 47 by a threaded connection. A plurality of limit springs 40 abutting against the mounting ring 47 are provided in the shaft sleeve 38, and a limit plate 42 is installed on the free end of the push rod 41, and a plurality of cones 43 are installed on the limit plate 42. In this way, when the walking mechanism 3 can rotate on the ground relative to the first platform 1, the shaft sleeve 38 connected to the frame 27 approaches the first platform 1 on the guide cylinder 44. At this time, the mounting ring 47 located in the shaft sleeve 38 is squeezed, forcing the push rod 41 to push the limit plate 42 to approach the ground, and gradually embed the cone 43 set on the limit plate 42 into the ground, thereby increasing the friction force when the walking mechanism 3 contacts the ground, and preventing the working platform 2 in the above-mentioned structure from applying a downward pulling force to the entire mechanism during the reciprocating motion of the telescopic structure 4 along the extension direction of the slope driven by the pushing mechanism, causing the above-mentioned structure to slip on the slope, posing a safety risk to the transportation of objects or operators.

[0043] Lifting methods for slope reinforcement materials: First, the telescopic structure 4 is dragged onto the slope by the walking mechanism 3, and the actual length of the telescopic structure 4 is adjusted; The first platform 1 located on the upper side of the walking mechanism 3 is kept relatively balanced on the horizontal plane by the positioning mechanism; The walking mechanism 3 is rotated relative to the first platform 1 on the ground, and the push rod 41 in the shaft sleeve 38 pushes the limit plate 42 to approach the ground, and gradually embeds the cone 43 set on the limit plate 42 into the ground; The operator controls the extension and retraction of the first push rod 5 to make the work platform 2 and the telescopic structure 4 move in a circle through the rotation point formed by the displacement seat 11, so that the horizontal angle of the work platform 2 changes and always maintains relative balance with the horizontal plane; Subsequently, the pushing mechanism is started to make the chain structure move obliquely upward along the guide channel in the guide member 7, and apply a thrust to the displacement seat 11 to make the working platform 2 move along the extension direction of the guide groove 35, thereby lifting the working platform 2 to a predetermined height.

[0044] The above are only preferred embodiments of the present invention and are not intended to limit the present invention.
